Two Vietnamese men who claimed to have explosives in their luggage in Tan Son Nhat Airport this week are fined VND4 million and will face intensified airport security check whenever they take a flight until next January.

Tran Van Dai, 35, and his brother Tran Van Dien, 32, will have to go through all steps of the security search, including full-body searches, whenever they check in any airport across the country between Jan. 15, 2014 and Jan. 14, 2015, according to a decision issued by the Civil Aviation Administration.

On Tuesday, Dai and Dien were checking in for a Jetstar Pacific flight from Ho Chi Minh City to Hanoi at 8 p.m. when they were asked by a ground service worker if if they were carrying any fragile goods in their luggage.

"Yes, a mine," Dai said.

When the worker asked again if he meant to say "mì", which means noodle in Vietnamese and sounds like "mìn", which is mine, both Dai and Dien replied, "bomb and mine."

The incident was reported to the airport authorities, and the two brothers were not allowed to board the flight, which took off on schedule.
